These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

to give you some better orientation of there numbers.. this is more or less how it actually looks like in the program.
If you want specific powder data I can do that too.
Bullet : .284, 175, Sierra SPBT 1940
Useable Case Capaci: 88.355 grain H2O = 5.737 cm³
Cartridge O.A.L. L6: 3.650 inch = 92.71 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 60000 psi, or 413 MPa
or a maximum loading ratio or filling of 105 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet

to give you some better orientation of there numbers.. this is more or less how it actually looks like in the program.
If you want specific powder data I can do that too.

Check out US-869.
Some of the data listed matches H-870 exactly.
It's also right next to 870 on the chart.

I've had 2 8lb jugs forever and have never opened them. I originally bought them to replace H870 but reports at the time were saying it wasn't even close. I've been using Retumbo, and i had good loads on a hot day and thought i would never have pressure with them and a year later they were all over pressure. No idea what that's all about. I've been wanting to try RL33 but it extinct as far as I can tell.
